In 10yrs who's to say MS or even Nintendo won't exceed the PS3? In fact I woulndn't be surprised if Nintendo or MS coming out with a full body motion sensor to make games totally interaction. Imagine actually "running" away from an enemy or squatting or jumping to dodge attacks? The Wii-mote and the nunchuck thing is just the beginning. When all this happens in a few years, where would the PS3 be?
